The BIOS usually includes features such as "Supervisor" or "User" passwords.
On a desktop computer, those strings are stored in the Southbridge CMOS
RAM. To remove the passwords, you could use the "Clear CMOS" jumper,
with the power off. Or, with the power off, you can pull the CMOS
battery, and then the passwords would be erased as well. The purpose of
a BIOS password, is to either protect the settings on the computer, or
prevent the computer from booting.
On certain laptops, the BIOS password implementation is much more dangerous.
Some laptops store the BIOS password in a serial EEPROM, not in volatile
CMOS RAM (volatile when you pull the battery). To get the password reset
on one of those, requires sending it to the manufacturer. Either that, or
some nice European chaps will sell you a kit, to reset it yourself. In such
cases, it pays to read the product documentation carefully, to see what would
happen if you forgot the password.
So on your average desktop computer, it isn't much security at all. In
other cases, the password could be "overly secure", meaning you could
be inconvenienced some day, by your attempts to secure the machine.
If the password were to be stored inside the BIOS EEPROM chip, a trip to
badflash.com and the usage of a replacement chip, could remove
the protection for you.

OK. Back to the 500xl. This is about all I could find. It would seem
there were two 500xl models. And the Midway 4000820 uses an 865 chipset,
which seems different than the info I can find for this one. (Some docs
reference 845, others 865, and those are different generations.) Gateway
doesn't seem to acknowledge this model now. I tried archive.org but
can't make any progress there either. So no luck getting a manual.

Looks like it is "motherboard roulette" time...
Good luck,
